is the 16340 battery same as cr123 because ultrafire is saying its the same. im trying to buy a charger that chargers any type of battery like the trustfire charger. where are you guys finding a 3V cr123 batteries? i can only find 3.6v or 3.7v. also is there a difference between rcr123, cr123 and cr123a
? planning on buying the Silverbullet and the website said it takes two rcr123 but i cant find any. can i put 2 x 3.7v cr123a or 2 x 3.6v cr123 batts on the SB?
